James Cameron's 'Avatar' Sequels Delayed Again, Says Director.

James Cameron's "Avatar" sequels have been delayed again due to plans of making the four follow-up films simultaneously.

"Well, 2018 is not happening," Cameron told The Star. "We haven't announced a firm release date. What people have to understand is that this is a cadence of releases. So we're not making 'Avatar 2.' We're making 'Avatar 2, 3, 4 and 5.' It's an epic undertaking. It's not unlike building the Three Gorges dam. So I know where I'm going to be for the next eight years of my life."

"Avatar 2," the first of three sequels to Cameron's 2009 3D sci-fi blockbuster, would not be ready in time for its planned Christmas 2017 release. That was already the second delay for "Avatar 2," which Fox had originally planned to release by Christmas of 2016.
